2015-08-11Stabilize the Duration APISteven Fackler-8/+8
This commit stabilizes the `std::time` module and the `Duration` type. `Duration::span` remains unstable, and the `Display` implementation for `Duration` has been removed as it is still being reworked and all trait implementations for stable types are de facto stable. This is a [breaking-change] to those using `Duration`'s `Display` implementation. Conflicts: src/librustc/lib.rs src/libstd/time/duration.rs
2015-07-29std: Fix sub-second Condvar::wait_timeout_msAlex Crichton-13/+14
The API we're calling requires us to pass an absolute point in time as an argument (`pthread_cond_timedwait`) so we call `gettimeofday` ahead of time to then add the specified duration to. Unfortuantely the current "add the duration" logic forgot to take into account the current time's sub-second precision (e.g. the `tv_usec` field was ignored), causing sub-second duration waits to return spuriously.
2015-07-21Auto merge of #27073 - alexcrichton:less-proc-fs, r=brsonbors-38/+50
This can fail on linux for various reasons, such as the /proc filesystem not being mounted. There are already many cases where we can't set up stack guards, so just don't worry about this case and communicate that no guard was enabled. I've confirmed that this allows the compiler to run in a chroot without /proc mounted. Closes #22642

2015-07-20std: Add IntoRaw{Fd,Handle,Socket} traitsAlex Crichton-4/+62
This commit is an implementation of [RFC 1174][rfc] which adds three new traits to the standard library: * `IntoRawFd` - implemented on Unix for all I/O types (files, sockets, etc) * `IntoRawHandle` - implemented on Windows for files, processes, etc * `IntoRawSocket` - implemented on Windows for networking types [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1174-into-raw-fd-socket-handle-traits.md Closes #27062

2015-07-11Auto merge of #26941 - fhartwig:osx-file-debug, r=alexcrichtonbors-3/+15
This makes `Debug` for `File` show the file path and access mode of the file on OS X, just like on Linux. I'd be happy about any feedback how to make this code better. In particular, I'm not sure how to handle the buffer passed to `fnctl`. This way works, but it feels a bit cumbersome. `fcntl` unfortunately doesn't return the length of the path.

2015-07-10Auto merge of #26751 - retep998:copy-that-floppy, r=alexcrichtonbors-1/+17
Using the OS mechanism for copying files allows the OS to optimize the transfer using stuff such as [Offloaded Data Transfers (ODX)](https://msdn.microsoft.com/en-us/library/windows/desktop/hh848056%28v=vs.85%29.aspx). Also preserves a lot more information, including NTFS [File Streams](https://msdn.microsoft.com/en-us/library/windows/desktop/aa364404%28v=vs.85%29.aspx), which the manual implementation threw away. In addition, it is an atomic operation, unlike the manual implementation which has extra calls for copying over permissions. r? @alexcrichton

2015-06-22Fix build on Android API levels below 21Geoffrey Thomas-0/+20
signal(), sigemptyset(), and sigaddset() are only available as inline functions until Android API 21. liblibc already handles signal() appropriately, so drop it from c.rs; translate sigemptyset() and sigaddset() (which is only used in a test) by hand from the C inlines. We probably want to revert this commit when we bump Android API level.
2015-06-22sys/unix/process: Reset signal behavior before execGeoffrey Thomas-2/+85
Make sure that child processes don't get affected by libstd's desire to ignore SIGPIPE, nor a third-party library's signal mask (which is needed to use either a signal-handling thread correctly or to use signalfd / kqueue correctly).
2015-06-22sys/unix: Consolidate signal-handling FFI bindingsGeoffrey Thomas-268/+199
Both c.rs and stack_overflow.rs had bindings of libc's signal-handling routines. It looks like the split dated from #16388, when (what is now) c.rs was in libnative but not libgreen. Nobody is currently using the c.rs bindings, but they're a bit more accurate in some places. Move everything to c.rs (since I'll need signal handling in process.rs, and we should avoid duplication), clean up the bindings, and manually double-check everything against the relevant system headers (fixing a few things in the process).
2015-06-22sys/unix/c.rs: Remove unused codeGeoffrey Thomas-75/+5
It looks like a lot of this dated to previous incarnations of the io module, etc., and went unused in the reworking leading up to 1.0. Remove everything we're not actively using (except for signal handling, which will be reworked in the next commit).
2015-06-19liblibc: Fix prototype of functions taking `char *const argv[]`Geoffrey Thomas-1/+1
The execv family of functions do not modify their arguments, so they do not need mutable pointers. The C prototypes take a constant array of mutable C-strings, but that's a legacy quirk from before C had const (since C string literals have type `char *`). The Rust prototypes had `*mut` in the wrong place, anyway: to match the C prototypes, it should have been `*const *mut c_char`. But it is safe to pass constant strings (like string literals) to these functions. getopt is a special case, since GNU getopt modifies its arguments despite the `const` claim in the prototype. It is apparently only well-defined to call getopt on the actual argc and argv parameters passed to main, anyway. Change it to take `*mut *mut c_char` for an attempt at safety, but probably nobody should be using it from Rust, since there's no great way to get at the parameters as passed to main. Also fix the one caller of execvp in libstd, which now no longer needs an unsafe cast. Fixes #16290.

This commit stabilizes the following APIs, slating them all to be cherry-picked into the 1.1 release. * fs::FileType (and transitively the derived trait implementations) * fs::Metadata::file_type * fs::FileType::is_dir * fs::FileType::is_file * fs::FileType::is_symlink * fs::DirEntry::metadata * fs::DirEntry::file_type * fs::DirEntry::file_name * fs::set_permissions * fs::symlink_metadata * os::raw::{self, *} * os::{android, bitrig, linux, ...}::raw::{self, *} * os::{android, bitrig, linux, ...}::fs::MetadataExt * os::{android, bitrig, linux, ...}::fs::MetadataExt::as_raw_stat * os::unix::fs::PermissionsExt * os::unix::fs::PermissionsExt::mode * os::unix::fs::PermissionsExt::set_mode * os::unix::fs::PermissionsExt::from_mode * os::unix::fs::OpenOptionsExt * os::unix::fs::OpenOptionsExt::mode * os::unix::fs::DirEntryExt * os::unix::fs::DirEntryExt::ino * os::windows::fs::MetadataExt * os::windows::fs::MetadataExt::file_attributes * os::windows::fs::MetadataExt::creation_time * os::windows::fs::MetadataExt::last_access_time * os::windows::fs::MetadataExt::last_write_time * os::windows::fs::MetadataExt::file_size The `os::unix::fs::Metadata` structure was also removed entirely, moving all of its associated methods into the `os::unix::fs::MetadataExt` trait instead. The methods are all marked as `#[stable]` still. As some minor cleanup, some deprecated and unstable fs apis were also removed: * File::path * Metadata::accessed * Metadata::modified Features that were explicitly left unstable include: * fs::WalkDir - the semantics of this were not considered in the recent fs expansion RFC. * fs::DirBuilder - it's still not 100% clear if the naming is right here and if the set of functionality exposed is appropriate. * fs::canonicalize - the implementation on Windows here is specifically in question as it always returns a verbatim path. Additionally the Unix implementation is susceptible to buffer overflows on long paths unfortunately. * fs::PathExt - as this is just a convenience trait, it is not stabilized at this time. * fs::set_file_times - this funciton is still waiting on a time abstraction.
2015-06-09std: Tweak process raising/lowering implementationsAlex Crichton-48/+17
* Slate these features to be stable in 1.2 instead of 1.1 (not being backported) * Have the `FromRawFd` implementations follow the contract of the `FromRawFd` trait by taking ownership of the primitive specified. * Refactor the implementations slightly to remove the `unreachable!` blocks as well as separating the stdio representation of `std::process` from `std::sys::process`.

2015-05-19Auto merge of #25495 - alexcrichton:process-pid, r=aturonbors-0/+4
This commits adds a method to the `std::process` module to get the process identifier of the child as a `u32`. On Windows the underlying identifier is already a `u32`, and on Unix the type is typically defined as `c_int` (`i32` for almost all our supported platforms), but the actually pid is normally a small positive number. Eventually we may add functions to load information about a process based on its identifier or the ability to terminate a process based on its identifier, but for now this function should enable this sort of functionality to exist outside the standard library.

2015-05-14Auto merge of #24920 - alexcrichton:duration, r=aturonbors-38/+23
This commit is an implementation of [RFC 1040][rfc] which is a redesign of the currently-unstable `Duration` type. The API of the type has been scaled back to be more conservative and it also no longer supports negative durations. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1040-duration-reform.md The inner `duration` module of the `time` module has now been hidden (as `Duration` is reexported) and the feature name for this type has changed from `std_misc` to `duration`. All APIs accepting durations have also been audited to take a more flavorful feature name instead of `std_misc`. Closes #24874

2015-04-30std: Always check for EDEADLK in rwlocks on unixAlex Crichton-2/+24
Apparently implementations are allowed to return EDEADLK instead of blocking forever, in which case this can lead to unsafety in the `RwLock` primitive exposed by the standard library. A debug-build of the standard library would have caught this error (due to the debug assert), but we don't ship debug builds right now. This commit adds explicit checks for the EDEADLK error code and triggers a panic to ensure the call does not succeed. Closes #25012
